USING
THE CURSOR
The
display
screen
contains
a marker
that
moves
like
a
"bouncing
ball" to indicate
the next
place
on
the screen
where
keyboard
input will appear.
The
marker,
called
the
cursor,
is in the shape
of a flashing
underscore.
Figure
2.8 at left illustrates
the cursor.
When
keys
are
pressed
on
the
keyboard,
the
entered
characters
are
displayed
on
the
screen
and
the
cursor
advances
with
each
new
keystroke.
You
may
move
the
cursor
by pressing the arrow
keys located
near
the
10-key
pad.
If
you
press
the
CAPS
LOCK
key,
the
cursor
becomes
three horizontal
lines instead of one.
ADJUSTING
THE
DISPLAY
SCREEN
Now
that
you
have
characters
on
the
screen,
you
may
adjust
their
intensity
for your
eye comfort.
Simply
slide
the
control
labeled
BRIGHTNESS
from
DARK
to
BRIGHT
until
you
find
a
comfortable
setting.
(The
control
is
shown at left in Figure 2.9.)
Both the color and monochrome
display
have
the following
user
adjustable
controls:
Brightness,
Height,
V.Hold
and
Focus.
In addition,
the monochrome
display has
an
adjustment
for
Contrast.
A Termination
Switch
is located
on the
back.
If
you
are
using
only
one
monochrome
display,
the
Termination
Switch
should
be set to 75
ohms.
If you
are
employing
more
than
one
display
unit
(up
to
four),
the
switch
on
each
display
should
be set
to infinity,
except
for the
last display
in the chain.
The
switch
on
the
last
display should
be set to 75 ohms.
